A gateway for data communication in a vehicle includes: a first communication interface, configured to use a first communication protocol; and a second communication interface configured to use a second communication protocol. The gateway is configured to transmit data from the first to the second communication interface and to transmit data from the second communication interface to the first communication interface. The gateway further includes a media converter configured to convert quality of service information from the first to the second communication protocol and from the second to the first communication protocol.

A system and method is disclosed of extracting information from real-time network packet data to analyze connectivity data for client devices in a network. The method includes: detecting when client devices initiate a connectivity event; after detecting a connectivity event, waiting a period of time for the client device to either reach or fail to reach a network connected state; after waiting a period of time, recording connectivity event information; and sending the recorded connectivity event information to an analytics system for network incident and/or network congestion analysis.

Methods for tracing a packet in a pipeline comprising a set of tables, in an SDN using OpenFlow. The packet comprises a trace bit, and is provided with a TTL value. A first network node indicates to a second network node to have each flow table decrement the TTL value by 1, based upon the trace bit. The first network node initially sets the TTL to be 1, and then sends the packet to a first table in the second network node. The first network node receives the packet, from another table in the set, and for every remaining table, and one table at a time: a) increments the TTL value by 1, and b) repeats the sending, and the receiving, until a last table is reached or a criterion is met. The first network node then indicates a route followed by the packet.

In some aspects, a method of the technology can include steps for sending a packet along a service function chain (SFC) to an egress node, the SFC comprising a plurality of service function forwarders (SFFs), wherein each SFF is associated with at least one service function (SF), and receiving the packet at a first SFF in the SFC, wherein the first SFF is associated with a first SF. In some aspects, the first SFF can also be configured to perform operations including: reading an option flag of the packet, and determining whether to forward the packet to the first based on the option flag. Systems and machine-readable media are also provided.

The present invention offers a network management technique that can realize effective acquisition of various data transmitted from terminals, while reducing the network congestion. In a network management system including a plurality of terminals that can transmit data, a plurality of destination devices that perform respective predetermined processes based on the data, a relay device arranged between them, and a management device communicable with the terminals, the destination devices, and the relay device, the management device receives a request regarding required data from the destination devices; and, in response to the request, instructs to integrate data items that are to be relayed to individual destination devices. Upon receipt of the instruction, the relay device identifies and integrates data items that are to be relayed to the individual destination devices from among data items transmitted from the terminals, and transmits the integrated data to corresponding ones of the destination devices, based on the instruction.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first wireless node may receive, from a second wireless node, a round-trip time timing advance indicator, wherein the round-trip time timing advance indicator is different from a timing advance indicator used for an uplink transmission timing advance message. In some aspects, the first wireless node may synchronize a timing configuration of the first wireless node to at least one of the second wireless node or a third wireless node based at least in part on the round-trip time timing advance indicator. Numerous other aspects are provided.

A domain name access method and a device are described. As described herein, a domain name server (DNS) server performs resolution on a domain name requested by the terminal device. The DNS server may then send an internet protocol (IP) address of an application server obtained through the resolution and use condition information to the terminal device. With this, communication efficiency of the terminal device can be improved, and waste of transmission resources in a communications system is also avoided.

Provided is a remote control system and a method enabling packets, related to a control signal and simultaneously transmitted from a controller to a plurality of controlled devices, to be received by the controlled devices without a difference in delay. Edge nodes 30 that are packet transfer devices are provided on communication paths between a controller 10 provided on a network and a plurality of controlled devices 20 provided in a location. The edge nodes 30 each include a transfer processing unit 31 that transfers the packets from the controller 10 to the controlled devices 20, and a timing control unit 32 that controls transmission timing of the packets in the transfer processing unit 31 to reduce a difference in arrival time of a plurality of packets simultaneously transmitted from the controller 10 to the plurality of controlled devices 20, at the plurality of controlled devices 20.

Aspects of the present disclosure provide techniques for reducing latency in distributing market data from a first location to one or more other locations over a wired or wireless transmission line. Some embodiments provide techniques for transmitting market data messages at a data transfer rate less than or equal to a predetermined target data transfer rate. Some embodiments provide techniques for transmitting only the most recent updates for a particular financial instrument. Some embodiments provide techniques which reduce or eliminate the need to recover a packet lost over the transmission line. Some embodiments provide techniques for aggregating data from multiple updates for a particular financial instrument into a single message for transmitting.
